Answer 2

\(\cdot\frac{203.204-1}{203.204}=\frac{203.204}{203.204}-\frac{1}{203.204}=1-\frac{1}{203.204}\)

\(\cdot\frac{204.205-1}{204.205}=\frac{204.205}{204.205}-\frac{1}{204.205}=1-\frac{1}{204.205}\)

Ta có: \(203.204< 204.205\)

\(\Rightarrow\frac{1}{203.204}>\frac{1}{204.205}\)

\(\Rightarrow1-\frac{1}{203.204}< 1-\frac{1}{204.205}\)

\(\Rightarrow\frac{203.204-1}{203.204}< \frac{204.205-1}{204.205}\)
